)

func main() {
	connConfig := z19.CreateSerialConfig()
	connConfig.Name = "/dev/serial0"

	port, err := serial.OpenPort(connConfig)
	if err != nil {
		panic(err)
	}
	defer port.Close()
	concentration, err := z19.TakeReading(port)
	if err != nil {
		panic(err)
	}
	fmt.Printf("co2=%d ppm\n", concentration)
}
